Blind image blur assessment by using valid reblur range and histogram shape difference

作者:

Highlights:

• Reference-free, training-free and transformation-free automatic blur assessment.

• A reblur algorithm is proposed to create valid reblur range and reblur images.

• Blurriness is estimated from the shape difference of local histograms.

• Experiment results indicate high correlation with human perception of blurriness.

• The proposed method performs better than recent methods in the spatial domain.
